Got two solid pinion spacers from jt's parts and accessories to install in my 78 fj40 diffs since I'm installing 3.70 gears (had to get some multi drill flanges as well.) When I took the solid spacer out of the package I noticed its roughly 1-2 mm longer than the crush sleeve I removed. I didn't think much of it at first. First go I installed the solid spacer with no shims tightened the pinion nut to set preload and it stops before tightening the pinion shaft, a bit puzzled, I put my Ingersoll titanium 1/2 gun on it and let it loose, still doesn't tighten up. So I take the pinion nut off and remove the outer bearing, remove the spacer and upon inspection you can see where it was imprinted! Damn spacer is too long! Anyone else ran into this? Or even used one of these?
